Description
BACKGROUND OF THE INVENTION
[0001] The invention relates to a device and a method for disposal
of occupant protection devices/road user protection devices with a
pyrotechnic igniter. The method and the device are to be used
advantageously especially with demounting or scrapping and scrap
recycling of motor vehicles to be disposed of.
[0002] In particular, in motor vehicles occupant protection
devices/road user protection devices with pyrotechnic igniters, for
example airbags, belt tensioners, pedestrian protection &
roll-over systems, have become accepted today due to their fast
response time and their verifiable occupant protection effect/road
user protection effect. The occupant protection devices/road user
protection devices are fired by an activating order, which is
produced by a control device subject to the acceleration forces
acting onto the vehicle.
[0003] However, the issue, so far still largely unsettled, of
disposal of motor vehicles with an occupant protection devices/road
user protection devices of this type, is disadvantageous. Thus, it
is unjustifiable for reasons of safety of work and fire protection
to give vehicles with inactive pyrotechnic igniters and thus
pyrotechnic active material into the circle of scrapping and scrap
recycling.
[0004] Furthermore, the number of the occupant protection
devices/road user protection devices built into a vehicle will
continue to increase and will vary individually per vehicle
according to the respective customer preference for equipment, so
that also the clearness on the number and position of the
pyrotechnic igniters can get lost and expanding them is to
expensive and unreliable.
[0005] Divers solutions are already known for disposal of occupant
protection devices with pyrotechnic igniters.
[0006] From DE 197 53 058 C2 for example a method is known for
disposal of pyrotechnic igniters as well as a disposal device for
implementing the method, which gives a disposal firing order to an
igniter or to an intermediate control device and the igniter is
fired/the igniters are fired.
[0007] From DE 101 13 099 A1 for example a method is known for
disposal of airbags as well as a device for implementing the
method, for which demounting of the airbag can be simplified by
arranging a device in front of the airbag in its fitting position
for collecting gases or solid bodies and by firing the airbag, the
device being preferably embodied as a funnel with an exhaust
equipment arranged thereto.
[0008] With these above-mentioned devices and methods for disposal
of pyrotechnic igniters it is implicitly understood that the
communication for transmitting the disposal order in case of need
functions at any time faultlessly and malfunction-free,
respectively, when it comes to communication errors. As in the
software code corresponding routines must be implemented into the
control device of the vehicle for the occupant protection
devices/road user protection devices, so that a corresponding
disposal order can be supplied to the control device from outside,
this freedom from error comprises and extends, respectively, over
the entire life time of the system, so that for example an
erroneously faulty interpretation of a simple communication
sequence with the control device, as this has to be effected in the
garages for service purposes, does not cause or may cause an
undesired faulty activation of all occupant protection devices/road
user protection devices. Likewise it must be ensured that by a
simple fault in the software operation of the control device in the
vehicle for the occupant protection devices/road user protection
devices, such as for example a so-called "code-run-away", the
software routines/software codes, implemented in the control
device, for disposal cannot inadvertently be activated, or in case
this shall happen, this does not result in the undesired effects in
case of fault.
[0009] It is, therefore, the object of the invention to
indicate/create a method for disposal as well as a device/a control
device by means of which both a reliable disposal of the device as
well as a stable/malfunction-free placing of the device in
operation can be ensured with implemented disposal
capabilities/disposal routines (protection from faulty activations
in the event of simple errors).
SUMMARY OF THE INVENTION
[0010] This object is achieved by a method for disposal of road
user protection devices with at least one pyrotechnic igniter, in
which a disposal firing order is provided to the igniter (3.1.1,
3.2.1) or to an intermediate control device (2) and in which the
igniter (3.1.1, 3.2.1) is fired, characterized in that the
transmission of the disposal firing orders to the igniter (3.1.1,
3.2.1) or to the intermediate control device (2) is effected each
on at least two different, separated and independent interfaces
(6.1, 6.2, 4.1, 4.2, 4.3) and that decoding of the disposal firing
order initiated from outside is effected in the control device (2)
by means of at least two different, separated and independent units
for signal decoding (7.1, 7.2) and that the forwarding is effected
to at least two different, separated and independent signal paths
(4.1, 4.2, 4.1.1, 4.2.1, 4.2.2, 4.1.2).
[0011] The invention is based on the idea to have an activation of
the disposal effected by means of disposal orders which are
supplied from outside, contrary to an activation order in the case
of a crash which is subject to acceleration or over-rolling, for
obtaining the above-mentioned safety in relation to simple errors
the disposal firing order being effected or transmitted to the
igniter/s or to an intermediate control device such that the
transmission of the disposal firing order and the transmission of
the disposal firing order which is initiated from outside is
effected on at least two separated/different interfaces.
[0012] In the following example of embodiment according to the
invention no further, detailed reference is made to the individual
functional principles of the already mentioned basic solutions, as
the respective functional principle or the contents of the
respective scripts, can be regarded as being included in its
entirety by the cross reference and can be considered as the state
of art, respectively.
[0013] To simplify matters in the following partly only individual
terms are used, whereas it is to be kept in mind that in this
connection also the accompanying components necessary for a system
are to be understood or incorporated/included, as the case may
be.
[0014] In the description and in the associated drawings those
terms and associated reference numerals are used, which are used in
the list added below.
[0015] In the following the invention is to be further described on
the basis of an example of embodiment with the aid of FIGS. 1 to 6.
It must be noted that for simplifying matters mostly only the
umbrella term of a system cited as a representative is used in the
figure description. It goes without saying that these include also
other systems with a comparable functional principle or devices
with analogous functions.

DETAILED DESCRIPTION OF THE DRAWINGS
[0023] FIG. 1 shows a principal possible realisation for disposal
of the active protection devices of an occupant protection system
with pyrotechnic igniters according to the invention. Depending on
the type of the occupant protection system in the vehicle (1), it
consists in the simplest version of a control device (2) and the
associated airbags, such as for example the driver airbag (3.1),
consisting of a pyrotechnic igniter, a gas generator and an airbag,
and the co-driver airbag (3.2), in turn consisting of a pyrotechnic
igniter, a gas generator and an airbag. The control device includes
the electrical power switches (not shown in detail in this drawing)
and the interface lines (4.x) provided for this purpose, which in
the case of a crash are necessary to transmit an activation order,
which is subject to acceleration or over-rolling, to the
pyrotechnic igniter.
[0024] The control device (2) has at least two separated/different
interfaces (6.1, 6.2), which are supplied to the diagnostic
connector (5)/to the diagnostic adapter (5) of the vehicle to
ensure a diagnosis of the control device (2) from outside in the
case of a service or in the garage operation by at least one
interface to the control device (2), to verify for example the
error storage of the control device.
[0025] Analogue to the garage service tester the diagnostic
connector (5)/at the diagnostic adapter (5) of the vehicle, as is
shown in FIG. 1, the device (8) can be connected for producing a
disposal firing order/disposal order, the disposal order having to
be effected for safety reasons according to the invention, as above
described, via at least two separated/different interfaces (6.1,
6.2).
[0026] In the simplest case the first interface (6.1) is for
example a so-called CAN-bus and the second interface (6.2) is a
further CAN-bus or a communication line, such as e.g. a
PAS-interface, a K-line, a VAN-interface, a modulated energy supply
line (clamp 15) or the like, already existing in the vehicle (1)
and at the control device (2), respectively. Depending on the type
of the respective interface this may be a one-wire, two-wire or
multi-wire interface.
[0027] A further advantage, which results in addition to the
desired realisation of a stable/malfunction-free disposal firing
possibility, is that with the use of interfaces (6.1, 6.2) already
existing in the vehicle (1) and at the control device (2),
respectively, no further/additional costs are required for the
placement of interfaces (lines, plug pins & interfaces)
necessary for this purpose.
[0028] FIG. 2 shows a principal possible realisation for disposal
of the active protection devices of an occupant protection system
with pyrotechnic igniters according to the invention, supplemented
with details.
[0029] The occupant protection system in the vehicle (1) is shown
analogously to FIG. 1, and is supplemented with two so-called
sourced-out assistant sensors (9), which are each connected to the
centrally arranged control device (2) by means of an interface
(9.1) to enable the assistant sensors to transmit their crash
relevant information to the control device (2).
[0030] The so-called out-sourced assistant sensors (9), which are
attached as close as possible to the vehicle body shell, are
sensors for monitoring and detecting the forces and accelerations,
respectively, acting onto the vehicle (1) to ensure in the case of
a crash relatively fast activation times for the road user
protection system/occupant protection system.
[0031] As can be further seen from FIG. 2, in this case for example
the interface (9.1) to the one assistant sensor (9) is combined
with the interface (6.2) (what is, however, not mandatory), since a
communication request as a rule is required/effected only from a
connected communication-capable unit (8, 9), as the two purposes
(crash activation request & disposal firing request) more or
less exclude each other. As is further implied in the figure, also
the other interface (9.1) to the other assistant sensor (9) can be
combined with the interface (6.1) (however, not mandatory), as far
as the two communication-capable units (8, 9) have the same
physical interface.
[0032] For effecting the desired disposal firing, at two
separated/different interfaces (6.1, 6.2) one disposal activation
request/disposal firing order each is applied/arranged
simultaneously or concurrent in time, so that at least for a
certain defined time concurrently closing of the power switch/es
LOW/of the interface/s L (4.1) and of the power switch/es HIGH/of
the interface/s H (4.2) is effected. As far as, as shown in the
figure, several pyrotechnic igniters or more than one occupant
protection device are to be disposed of, it has proven to make
sense that the protocol for activating the disposal firing is to be
interpreted such that each individual pyrotechnic igniter can be
activated individually/separately so that for example the pressure
development in the vehicle (1) generated during the disposal firing
can be kept defined to a certain degree.
[0033] The protocol or the protocol contents of the corresponding
interface (6.1, 6.2), which is to be used for effecting the
disposal firing, in particular in case for example the interface
(9.1) is combined with the interface (6.2), is to be preferably
chosen in such manner that an order, which is supposed to initiate
a disposal firing, is defined on the interface (6.2) in such manner
as it is not provided for in the defined protocol scale of the
assistant sensor (9) and on its interface (9.1), respectively.
However, as an alternative, the protocol or the protocol contents
of the corresponding interface (6.1, 6.2) can also be deliberately
chosen, in particular if the protocol depth is relatively
restricted, in such manner that an order, which is supposed to
initiate a disposal firing, is defined on the interface (6.2) in
such manner as it corresponds to an activation request information
of the assistant sensor (9) in the defined protocol scale of the
assistant sensor (9) and on its interface (9.1), respectively. The
latter is especially relevant if the unit for signal decoding (7.2)
and the unit for level conversion (7.2), respectively, which
preferably is realised as an ASIC or as a monitoring unit in an
ASIC, or as a .mu.P, has activation-capable algorithms.
[0034] FIG. 3 shows a detailed representation of a control device
(2) for disposal of the active protection devices of a road user
protection system/occupant protection system with pyrotechnic
igniters according to the invention.
[0035] The in accordance with the invention at least two
separated/different interfaces (6.1, 6.2) of the control device (2)
are supplied here to two separated/different units (7.1, 7.2) which
are independent to each other. The first unit (7.1), which in this
case for application reasons is for example the algorithm,
implemented for evaluating the crash-relevant signal courses, which
are subject to acceleration or over-rolling, of the forces and
accelerations, respectively acting onto the vehicle (1), serves as
a unit for signal decoding (7.1) and as a unit for level conversion
(7.1), respectively, and is preferably realised as an ASIC or as a
monitoring unit in an ASIC or as a .mu.P.
[0036] The outputs of the at least two separated/different units
(7.1, 7.2), which are independent to each other, are each connected
by means of the connecting appropriate control lines (4.1.1, 4.2.1)
to the current-capable power switches HIHG/interfaces H (4.2) and
current-capable power switches LOW/interfaces L (4.1) necessary for
the disposal firing in the firing circuit. The outputs (4.2.2) of
the current-capable power switches HIHG/interfaces H (4.2) are
connected to the pyrotechnic igniters (3.1.1, 3.2.1) for the driver
airbag (3.1) and the co-driver airbag (3.2), which with their
second connection are each connected to the input (4.1.2) of the
current-capable power switches LOW/interfaces L (4.1).
[0037] As soon as the at least two separated/different units (7.1,
7.2), which are independent to each other, receive a disposal
activation order via the interfaces (6.1, 6.2), they initiate a
closing of the current-capable power switches HIHG/interfaces H
(4.2) and current-capable power switches LOW/interfaces L (4.1), so
that current can flow from the energy storage (10.1), which is
charged by the power supply (10) not shown in detail of the control
device (2), via the pyrotechnic igniters (3.1.1, 3.2.1), which
current flow finally results in the desired activation of the
pyrotechnic igniters (3.1.1, 3.2.1) or for disposal firing of the
pyrotechnic igniters (3.1.1, 3.2.1) plus the protection devices
connected thereto, such as driver airbag (3.1) and co-driver airbag
(3.2).
[0038] FIG. 4 shows a detailed representation of the control device
(2) for disposal of the active protection devices of a road user
protection system/occupant protection system with pyrotechnic
igniters according to the invention.
[0039] The in accordance with the invention at least two
separated/different interfaces (6.1, 6.2) of the control device (2)
are supplied here analogue to FIG. 3 to two separated/different
units (7.1, 7.2) which are independent to each other. In addition,
in contrast to FIG. 3, in this example of embodiment a third power
switch/an interface 3 (4.3) is located between the energy storage
(10.1) of the control device (2) and the current-capable power
switches HIHG/interfaces H (4.2).
[0040] Other than in FIG. 3, in FIG. 4 triggering of the
current-capable power switches HIHG/interfaces H (4.2) and
current-capable power switches LOW/interfaces L (4.1) is effected
by means of the connecting appropriate control lines (4.1.1, 4.2.1)
through the unit 1 for signal decoding (7.1). Triggering of the
third power switch/interface 3 (4.3) is effected in this example by
means of the connecting appropriate control lines (4.3.1) through
the unit 2 for signal decoding (7.2). Thus, it is ensured also in
this example of FIG. 4 (analogue to FIG. 3) that a disposal firing
is effected each via two separated/independent/different signal
paths as also via at least two separated/independent/different
circuit parts, so that the desired stableness/interference
resistance against an unintended disposal firing can be ensured
also in case of the occurrence or existence of a simple error.
[0041] As a further possibility to obtain the desired
stableness/interference resistance against an unintended disposal
firing, the realization not shown in detail is to be taken into
consideration, in which the firing energy required for disposal is
supplied especially destined for disposal firing by means of a
first interface (supply line) (6.1, 6.2) statically or dynamically
(instead of the energy storage (10.1) of the control device (2))
from outside, and in which by means of a further interface (6.1,
6.2) and a unit 1 or a unit 2 for signal decoding (7.1, 7.2) the
vital order for disposal firing is transmitted.
[0042] FIG. 5 shows a principally possible realization for disposal
of the active protection devices of an occupant protection system
with pyrotechnic igniters according to the invention, shown as a
BUS-realization/"firing-BUS-airbag-realization".
[0043] Other than in FIG. 3, the power switches HIHG/interfaces H
(4.2) and power switches LOW/interfaces L (4.1) required for
disposal firing of the pyrotechnic igniters (3.1.1, 3.2.1) are not
located in the control device (2), but in the so-called IPEs
(Integrated Peripheral Electronic Units) (12), which are connected
by a BUS-connection (11) in the vehicle to the control device (2)
and to the BUS-interface-driver-unit (7.3) provided for this
purpose in the control device (2).
[0044] The BUS-interface-driver-unit (7.3) is connected on the
input side to the two outputs of the two separated/different units
(7.1, 7.2), which are independent to each other, to receive the
corresponding control orders, such as for example the disposal
firing control order by the two separated/different units (7.1,
7.2), which are independent to each other, and to lead/transmit
them by means of the BUS-connection (11) in the vehicle to the
so-called IPEs (Integrated Peripheral Electronic Units) (12), or to
the pyrotechnic igniter (3.1.1, 3.2.1) which is connected thereto,
in order to initiate there a disposal firing.
[0045] FIG. 6 shows a chronological representation of the
transmission/realization/implementation of the disposal firing
order.
[0046] At the first interface (6.1), as is shown, a disposal firing
order is applied from externally/outside, which according to FIG. 3
in the control device results in/effects closing for a defined time
of the power switch/es LOW/of the interface/s L (4.1). If at the
second interface (6.2) simultaneously or with a certain concurrence
in time a disposal firing order is also applied from
externally/outside, which again in the control device for a defined
time results in/effects closing of the power switch/es HIGH/of the
interface/s H (4.2), this leads to the desired disposal firing of
the road user protection devices, which for reasons of clearness
alternatively are shown in FIG. 6 only as pyrotechnic igniters
(3.1.1, 3.2.1) for the driver airbag (3.1) and for the co-driver
airbag (3.2). The power switches HIHG/interfaces H (4.2) and power
switches LOW/interfaces L (4.1) required here for disposal firing
of the pyrotechnic igniters (3.1.1, 3.2.1) can be located, as
implied by the dashed lines, either in the IPEs (Integrated
Peripheral Electronic Units) (12), as far as this is a so-called
"firing-BUS-airbag-realization", as is shown in FIG. 5, or in the
control device (2), as far as this is for example a so-called
conventional/standard "central-airbag-realization", as it is shown
